Machine configuration: underfloor pit-mounted dual Spindle milling machine, capable of simultaneously re-profiling both wheels of a railway wheelset using the axle centers as the machining reference point.

It is capable of profiling wheelsets to necessary specifications concentrically and plane dimensions in any of the following situations:
1- While the wheelset is under a locomotive, passenger or freight car, transit vehicle, or other rolling stock.
2- While the wheelsets are mounted in a truck.
3- While the wheelset is demounted as a single set.

Includes a large pallet of new parts/spares.
We also have 3 sets of Cutting heads (most have never been used).
The Machine will re-profile both wheels simultaneously to equal diameters, leaving a witness groove at the flange of the profile. Both wheels of a wheelset will be finished automatically to the diameter that is required to clean up while removing the minimum amount of metal possible.
